Easy Guinness Chocolate Cake with Baileys Frosting

This is the ultimate and only Guinness chocolate cake recipe you'll ever need because it's so incredibly easy to make in just one bowl-no mixer needed! The rich and decadent chocolate flavor is deepened by the almost coffee like flavor of Guinness Stout which is used in the cake batter, and also brushed on the cake layers before frosting. Fill and frost with this Bailey's frosting, and you've got yourself a boozy and chocolatey cake worth celebrating with!

Ingredients

  • 2 ½ cups granulated sugar, 500 g
  • 2 ½ cup all purpose flour, 312.5 g
  • 1 cup cocoa powder, 86 g
  • 2 tsp baking soda
  • 1 tsp baking powder
  • ¼ tsp kosher salt
  • cup vegetable oil
  • 1 cup Milk
  • 3 eggs, room temp
  • 2 tsp vanilla extract
  • 1 cup Guinness Stout

Instructions
 

  • Preheat the oven to 350° F.
  • In a large bowl combine the 2 ½ cup sugar, 2 ½ cup flour, 1 cup cocoa powder, 2 tsp baking soda, 1 tsp baking powder, and ¼ tsp salt. Whisk lightly to combine.
  • Add in the 1/3 cup oil and whisk again. It might be a little hard to mix but it’s ok.
  • In a measuring cup add the 1 cup milk, 3 eggs, and 2 tsp vanilla extract. Whisk and pour into the batter. Whisk again till a batter starts to form.
  • Pour in the 1 cup Guinness and mix well.
  • Spray 2, 9” round cake pans with baking spray. Pour the batter in evenly and bake for 30-35 minutes or until the tops are set and the cake starts to pull off from the side.
  • Cool the cakes for 10 minutes in the pan and then completely over a wire rack.
  • Meanwhile reduce the Guinness. Pour 1 cup of Guinness into a medium sized pan and let it come to a boil over high heat.
  • Boil for 1 minute, then lower to a simmer for 10 minutes. The beer should be reduced by half and be dark and syrupy. Brush the reduced stout over the cakes, it’s ok if they are still a little warm.
  • Fill and frost the cakes with the frosting once completely cool.
